More flat file fun.

Here is what I want to do:
Create a .csv flat file. It has 8 columns and 4 rows.
The columns will always be the same.
The 4 rows represent 4 different products.

I want to create a data entry sheet where I will enter information regard
each of the 4 products.
This information will be pulled into the .csv file with "|" as the delimiter.

Is this possible? How can I not lose the referential information?
